vim-plug travis-ci

A minimalist Vim plugin manager.

Pros.

  • Easier to setup: Single file. No boilerplate code required.
  • Easier to use: Concise, intuitive syntax
  • Super-fast parallel installation/update (requires +ruby or Neovim)
  • On-demand loading to achieve fast startup time
  • Post-update hooks
  • Can choose a specific branch or tag for each plugin
  • Support for externally managed plugins

Usage

Download plug.vim and put it in ~/.vim/autoload

mkdir -p ~/.vim/autoload
curl -fLo ~/.vim/autoload/plug.vim \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Edit your .vimrc

call plug#begin('~/.vim/plugged')

" Make sure you use single quotes
Plug 'junegunn/seoul256.vim'
Plug 'junegunn/vim-easy-align'

" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Using git URL
Plug 'https://github.com/junegunn/vim-github-dashboard.git'

" Plugin options
Plug 'nsf/gocode', { 'tag': 'go.weekly.2012-03-13', 'rtp': 'vim' }

" Plugin outside ~/.vim/plugged with post-update hook
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': 'yes \| ./install' }

" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'

call plug#end()

Reload .vimrc and :PlugInstall to install plugins.

call plug#end()

On-demand loading of plugins

" NERD tree will be loaded on the first invocation of NERDTreeToggle command
Plug 'scrooloose/nerdtree', { 'on': 'NERDTreeToggle' }

" Multiple commands
Plug 'junegunn/vim-github-dashboard', { 'on': ['GHDashboard', 'GHActivity'] }

" Loaded when clojure file is opened
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Multiple file types
Plug 'kovisoft/paredit', { 'for': ['clojure', 'scheme'] }

" On-demand loading on both conditions
Plug 'junegunn/vader.vim',  { 'on': 'Vader', 'for': 'vader' }

for option is generally not needed as most plugins for specific file types usually don't have too much code in plugin directory. You might want to examine the output of vim --startuptime before applying the option.

Post-update hooks

There are some plugins that require extra steps after installation or update. In that case, use do option to describe the task to be performed.

Plug 'Valloric/YouCompleteMe', { 'do': './install.sh' }

If you need more control, you can pass a reference to a Vim function that takes a single argument.

function! BuildYCM(info)
  " info is a dictionary with 3 fields
  " - name:   name of the plugin
  " - status: 'installed', 'updated', or 'unchanged'
  " - force:  set on PlugInstall! or PlugUpdate!
  if a:info.status == 'installed' || a:info.force
    !./install.sh
  endif
endfunction

Plug 'Valloric/YouCompleteMe', { 'do': function('BuildYCM') }

Both forms of post-update hook are executed inside the directory of the plugin and only run when the repository has changed, but you can force it to run unconditionally with the bang-versions of the commands: PlugInstall! and PlugUpdate!.

Make sure to escape BARs and double-quotes when you write do option inline as they are mistakenly recognized as command separator or the start of the trailing comment.

Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }

But you can avoid the escaping if you extract the inline specification using a variable (or any Vimscript expression) as follows:

let g:fzf_install = 'yes | ./install'
Plug 'junegunn/fzf', { 'do': g:fzf_install }
